Use a dry cleaning brush to remove surface dirt and debris.
Attach an upholstery brush to your vacuum cleaner. Remove and vacuum the cushions, vacuum the underlying fabric, and then enlist a helper to tip the sofa onto its back. Vacuum the underside, set the sofa back on its feet, and replace the cushions.
Fill a steam cleaner with water and upholstery detergent, referring to the instruction manual and the directions on the detergent bottle. Attach the upholstery nozzle to the cleaner, and move it over the sofa in parallel strokes.
